11.5. Cassandra Heatmaps

Cassandra can generate client-side heatmaps in GeoServer by defining a style and using the built in gs:Heatmap process within GeoServer.

To start, add a new SLD style to GeoServer named “heatmap” and use this sld clientside-heatmap.sld

Now you can change the style parameter to be styles=heatmap in the Layer Preview or PNG preview in GeoServer.
